What to seed into an old grass field for hay??

I am in central Ky and I have acquired about 60 acres of grass that has been neglected for the past 2-3 years. I have pulled all the saplings out and it seems to have a good thick undergrowth but I want the cover to be even thicker come spring to shade out the weeds. It will get lime ASAP and will get sprayed with 24d when the appropriate time comes. What should I broadcast on this ground for quick growth and thick growth? I use cereal rye as a cover crop on my grain ground but that I always seed in the fall. Can it be seeded in the spring? Would it be a good option? Anyways any advice you guys could give on a spring seeded plant to put in with the grass would be great! I want good hay off this piece but this year it will probably just be cattle hay. Thank you

I would just give it a good dose of Nitrogen this spring along with a good shot of 2-4d. See what you actually have in grasses and then form a plan for planting in the fall if needed. Doubtful if much would grow with a "thick undergrowth" of grass this spring anyway....a good dose of Nitrogen will do more for shading weeds out at this point. Your location in your profile would be helpful to all in our responses . Thanks.

What is something I could broadcast? This is around radio towers and they dont want any planting equipment used because of the underground radials? There are some spots that really have no grass that is why I would prefer to over seed some. Thank you
